Incorporating Planar Resistors in PCB DesignsPlanar resistors can provide a means of improving space utilization in PCB design.by Roy M. Signer, Engineering Dept. Manager, Ohmega Technologies, Inc., Culver City, Calif.Since the technology to include resistor elements in printed circuit board (PCB) design was introduced in early 1972, designers have had the opportunity to fabricate either on the surface or inside PCB's to the exact requirements of the circuit. The methods used to design the resistor elements using this technology are essentially the same as those used in the hybrid circuit industry.

BGA Termination AlternativesPlanar resistor technology offers both design flexibility and proven reliabilityby Bruce P. Mahler, Ohmega Technologies, Inc., Culver City, Calif.The space constraints of high-density BGA footprints have generated widespread interest in planar resistor technology (PRT). Standard thin film design rules are used to create resistors that are either partial squares or multiple squares of resistive material. Standard series and parallel termination resistors have therefore been mostly rectangular in shape. If you would like this entire article, please e-mail us, and we'll send you a copy.

SignerSingle- and double-sided printed circuit boards have become multilayer packages with increasingly finer line widths and spaces, hosting greater through hole and interconnection densities. Newer substrate materials and different methods of component and circuit attachments have become necessary. More and more, the complexity, sophistication and demands of electronic systems are focusing an integration of logic, circuit and package designs.
